Abstract

This article demonstrates the effectiveness of granular portfolio analysis versus deal-level portfolio analysis by applying each approach across two issues that continue to vex the non-agency RMBS market: the adequacy of seller-provided representations and warranties of loan quality and valuation techniques that can effectively reveal the hidden intricacies of loan performance and resulting RMBS bond cash flows. The article also illuminates how this methodology can be done as quickly, painlessly, and efficiently as traditional “higher level” portfolio evaluations.
